riggify face rig makes the eyes so error
In edit mode you can select a vertex, in the &quot;N&quot; properties panel you will be able to read its weight values in the &quot;vertex weights&quot; tab. If more than one vertex is selected you can copy the values of the active (last selected) vertex to the others.
When I use Rigify face rig, I generally add a correction shape key in order to flatten the eyelids and the lips, using drivers to automate the shape keys effects.
